SAFETY ENVELOPE:

Application filed March 17, 1923. Serial No. 625,822.

This invention relates to safety envelopes andh'as-for its main object torprovide an envelopein which money, checksor other valuable papers may be enclosed with perfect safetyandsealed in a secure way against unauthorized opening; of the same.

Another object, of this; invention isto provide an: envelope, of the character described, which may have comparatively large blank spaces and fields-in an open position before it is sealed, said fieldsbeing adapted to receive writing; and? carry the letter or other notes and; messages desired to be mailed in said envelope;

Still further objects will. be apparent and partly pointed out as: the specification will proceed..-

The invention consists in the combinations and arrangements of parts hereinafter described: and claimed- The invention will be best understoodby reference to f the accompanying drawings forming a part of this specification, and. in which:

Figure 1 is a developed plan View of modification of my invention;

Figure 2 shows the same form of my safety envelope in a closed position;

Figure 3 is a developed plan view of another modification of my invention, while Figures 4- and 5 show the rear and front sides, respectively, of said second modification of my safety envelope, as it would appear in a fully closed and sealed position.

Referring more closely to the drawings, the first embodiment of my invention, as shown in developed form in Figure 1, is composed of one integral piece of paper or other similar materials and has a central field 6, a lower field 7, two side fields 8 and 9, an up per flap and a side flap 11, of a peculiar shape. The message to be carried in the envelope may be written onthe fields 6, 7, 8 and 9, said fields being divided by the creases 12 and 13. After the message is written, the fields 7 and 9 are folded over the fields 6 and 8, whereupon the fields 8 and 9 together are folded down over the fields 6 and 7 the four fields now occupying a rectangular space identical to that of field 6 and having said field as a base. The envelope is sealed by folding the flap 10 over the combined four fields and pasting the edges of the same on the outside of the top field by glue, paste or other suitable means as is usually done with envelopes. To have a double security, the

one

flap. 11 is now folded over thewhole combination and pasted partly on. top of flap; l0

and partly on top ofthe; upper field 8. I also may fold and paste the flap; 11 first on the top field 8 and fold and paste flap 10 thereafter, reversing-the orderof the flapsl-O and 11. The rear side of" this: modification of my safety envelope would appear after being sealed as; shown in Figure 2, while the front of it would look like the envelopes: usedat present.

Another embodiment of my safety envelope is shown, in an extended developed form, in Figure 3. The main. body ofthis envelope is composed of three field's. 14-, 15 and 16,. adapted toi carrythe, messagev or the text of the letter. After having written said message or letter and having placed the money, checks or other valuables; to. be mailed in my envelope, the lower field 1.6 is folded on. the middle field: 1*5; alongside of the-crease 17. Thereupon the two. we tangu lar side flaps 1'8 and: 1191 are folded down on this combination and pasted: on. top

of the field 16, the whole now forming a pocket. Field 1 4% with its double flaps 2.0 and 21. and its top flap 22 is now'folded down on this pocket on the line of crease 23 and the flap 22 folded over the reverse side of field 15 and pasted thereon. The two side flaps and 21 are now pasted on top of both flap 22 and field 15, while their extensions 24: and 25 are further folded on the lines of crease 26 and 27, onto the front side of the envelope, that is on the outside of field 14, making an additional safety device against an unauthorized opening of .my safety envelope. The rear side of the second modification of my envelope would appear, after being sealed, as shown in Figure 4, while the front side of it would look as indicated in Figure 5. The postage stamp may thereupon be pasted over and. across side extension 24:, while the name and address of the sender may be written across the'other side flap 25. The name of the addressee can be written in the center of field 14 in the usual manner.

The several advantages of my safety envelope are obvious from the drawings and descriptions presented. My envelope is secured and sealed by several independent means so that their unauthorized opening is made almost impossible and if done. it can always be detected thereafter. The body of the envelope itself may easily serve for carrying t-hermessages or the text of'the letter, while my envelope forms a strong secure pocket for any of the valuables mentioned which it is desired to'be forwarded in said envelope. Upon receipt of the envelope, the addressee may cut the flaps of the same olf alongside of their creases and the whole c11- velope can be opened up into the form of a letter paper, with the greatest ease and facility. The edges of the flaps may also be made of an undulating or scalloping line, as at 28, thereby making the forcible opening of the same more difficult, since the edges of the flaps will be easily torn in the valleys of said undulating line.

I have used these safety envelopes of mine for mailing valuablesto Europe and while said valuables very often have been taken from ordinary envelopes so that the ad dressee could not notice the unauthorized opening of them, no valuables have ever been stolen since I have been using my new safety envelopes.

Having thus described my invention what I claim as new and'want to protect by Letters Patent is:

In a safety envelope having a main body formed and creased to comprise: three fields of equal size and shape, and rectangular end pasting flaps on the central one of said fields, a top pasting flap on the upper field having a centrally and outwardly widening contour with an undulating edge, two side pasting flaps of upwardly widening triangular shape and two top extension pasting flaps on said side pasting flaps in the shape of inwardly widening triangles, their outside edges continuing and completing the outside lines of said top and side flaps into one irregular design, but said top side pasting flaps being separated from said central top pasting flap by slits, said various flaps being separated from the body of the envelope and said top side flaps from said side pasting flaps by appropriate creases, so that when said envelope is formed by folding the three fields together and pasting the end flaps thereon in the manner described and shown, said central top pasting flap may be folded and pasted on the back of the same in' a downwardly curved line edge across about the center of the same, said side pasting flaps may be folded and pasted over the back of the envelope, and thetop pasting flap thereon, their edges providing inwardly inclined undulating lines across them starting from the lower corners of the envelope to the top edge of the same, and
